Description
Technical field
The disclosure relates to a kind of method for the preparation of absorbent assembly such as absorbent core.This absorbent assembly can be used for absorbent articles such as sanitary napkins, diaper, adult incontinence product etc.
Background technology
Generally known, in order to use air laid to manufacture absorbent assembly, preliminary election produces fiber used in the method and fibre debris by fibrous material such as paper pulp of milling.Those that it should be noted that natural fabric is such as made up of cellulose are by the web manufacture of the type.Described mill and pulverize preferably carry out being called as in hammer-mill, wherein fibrous material is fed on the cutting blade of the lateral alignment of cutting mechanism, and the multiple beating members impacts be wherein arranged on rotating cylinder are projected into one end of the fibrous material on cutting blade.
In the process forming the absorbent assembly being used for absorbent article, usually utilize the fibrous material provided with roll form, this allows the continuation method carrying out to run with relative two-forty.But compared with the fibrous material provided with each sheet-form, the fibrous material that can provide with roll form is quite limited, thus limits the type of the fibrous material of the absorbent assembly that can be used to for the preparation of absorbent article.
Although compared with roller form, more eurypalynous fibrous material can be provided by each sheet-form, but each fibre material sheets is difficult to use in for the preparation of the commercial-scale continuation method of absorbent assembly, because be difficult to keep constant mass flow, this is owing to being sent to so that when milling in hammer-mill separately when each sheet material, is tending towards forming gap between each sheet material described.
For to mill and the apparatus and method of pulverized fiber material are known, such as, can recognize from DE2245819A1.In the device that this is known, cutting blade is formed in housing by entrance of slotting, and described packaging shell has the rotating cylinder main body of multiple beating members.In the method, beating members is advanced the inner of slit and leaves narrow gap, and entered fibrous material is milled by the rotating cylinder main body rotated.The device of the type has shortcoming as large in next: if use the fibrous material of relative resilient, then produce the fibre debris of irregular.Because fibrous material has elasticity, therefore the fracture of fibrous material mainly occurs in outside cutting blade.
Therefore, in the prior art, a kind of following method and apparatus is known, utilizes described method and apparatus, and fibrous material is fixed by the additional clamp system in cutting blade region.This known method and known device are described in EP0386017B1.Herein, fibrous material is fed the cutting blade to cutting mechanism.Clamp system is arranged to and cutting mechanism short distance, and the feature of described clamp system is to be clamped in the lower surface of fibrous material and the relative clamping claw of two on upper surface.One in clamping claw is designed to movable, and thus this causes fibrous material to be clamped in a swing fashion.Therefore, this adds the additional stability of fibrous material in period of milling.
But, these known method and apparatus have a large shortcoming thus, because the time point that is milled of the time point that is clamped of fibrous material and fibrous material must be synchronized with each other to obtain the fibre debris that limits size in a continuous process and to keep constant mass flow.In addition, owing to there is interval between designed cutting mechanism and clamp system, this known method and apparatus is utilized also can not to produce superfine little fibre debris.
Therefore still need a kind of method for the preparation of absorbent assembly that improvement is provided, especially utilize each fibre material sheets to prepare these absorbent assemblies in a continuous process.
Summary of the invention
The present invention relates to a kind of each fibre material sheets that utilizes and carry out the method for preparation example as the absorbent assembly for absorbent article.Each fibre material sheets described is fed through the clamping gap clamp system and cutting mechanism, described clamping gap be designed to swing, wherein clamp system is directed to and makes clamping movement back and forth relative to cutting mechanism.
Method of the present invention can utilize a kind of as lower device, and wherein clamp system and cutting mechanism are arranged to toward each other to form clamping gap in flat clamping, and wherein clamp system can be directed to and make clamping movement back and forth relative to cutting mechanism.
